COVID-19 prompted rapid growth in the burgeoning social bond market, which grew sevenfold in a single year, Bloomberg New Energy Finance Figures show.
BNEF said the overall sustainable debt market, which barely existed 10 years ago and includes assets such as green bonds as well as social bonds, grew 29 per cent in 2020.
The money raised through social bonds goes towards projects with positive social impacts such as education, healthcare, housing and basic infrastructure.
Like social bonds, green bonds are generally issued by governments and supranational bodies such as the World Bank to fund environmentally friendly programs, generally aimed at mitigating climate change.
